Interment of John Glenn at Arlington National Cemetery

Glenn was the first American to orbit Earth on Feb. 20, 1962, in a five-hour flight aboard the Friendship 7 spacecraft. In 1998, he broke another record by returning to space at the age of 77 on the Space Shuttle Discovery.

“As we say our final goodbye today to a great American and NASA pioneer, we send our deepest sympathies to the family of John Glenn, and our heartfelt condolences to his devoted wife Annie on what would have been their 74th wedding anniversary.

“Senator Glenn was more than an astronaut – he was the hero we needed in a rapidly changing world and an icon of our American spirit. We will never forget him, and future generations will continue to live out his legacy as we venture farther into the solar system.
